To all whom it may concern:

Be it known that We, JAMES T. YATES and- JoHN DEVEY; citizens of the United States, and residents of Lehi, in the county of Utah and State of Utah, and WILLIAM B. RIGHAN and WALTER A. DEVEY, citizens of the United States, and residents of American Fork, in the county of Utah and State of Utah, have made certain new anduseful Improvements in Smoke and Fume Condensers, of which the following is a specification.

' Our invention is an improvement in fume arresters and condensers for the purpose of collecting and utilizing the escaping ,gases from metallurgical furnaces and thereby avoiding injury to vegetation, &c, .aswell as saving considerable proportions of gold, silver, copper, sulfur, arsenic, and other elements usually carried away and lost in the air. It is also designed to suppress and dispose of the smoke and gases arising from the combustion of coal and other fuel, so as to avoid the nuisance which such escaping smoke involves. 1 v

Our invention consists in a novel construction of tanks with means for introducing the gases in minute subdivisions and agitating the same in connection with a supernatant body of water for suppressing and collecting the available material of the smoke and gases with reference to the drawing, in which- Figure 1 is a sectional elevation. of the 'agltating tank and overflow tank connected Fig. 5 is a detail in to ether. Fig. 2-is a plan view of the revo ving smoke distributirig coils. Fig. 3 is a sectional plan view on line 33 of Fig. 1. Fig. 4 is a plan view of the overflow tank. pers motive of one of the baffle plates of the overii I detail pers ective of one pair of the beater arms, and' ig. 7 is an enlargedsectional detail on line 7-7 of Fig. 1.

The usual arrangement of our fume arrester and condenser is shown in the sectional view of Fig. 1, and comprises two principal ele- .ments, the one-an elevated scrubber tank closed at both top and bottom, as shown at A on the right hand side, and the other an overflow settling tank P, shown on the left hand side of Fig. 1, the two being connected by a pi 'e K emerging from the top of tank A and delivering into the bottom of tank P. The scrubber tank A is preferably of cylinow. tank. Fig. 6 is a drical form and made of'sheet metal, or any other desired material, and is com osed of a series of superposed sections etachably united. These sections consist of the upper section A the three shorter sectionsA, A A and two subjacent sections-A, A of larger size. their meeting edges with right angular flanges connected together by bolts and there is secured between them at these points of union, reticulated screens 0, 0, O 0 0. Between the reticulated screens 0 0, an

I inlet pipe B enters the side wall of the section A an being suitably clamped thereto by flanges and bolts, extends to the middle of the tank, where it communicates with a central boxing D, having acked stuffingbox glands at the top and bottom. This boxing B is stayed inposition by one or more cross braces X.

Centrally through the boxing D there passes a vertical ho low shaft F, whose lower end is pivoted upon bottom of the tank. The upper end of this hollow shaft is connected to and rotated by a transverse shaft T through the medium of the bevel gears E, the said shaft T deriving motion from a sprocket wheel W outsideof the tank, which is suitably driven by a chain.

The driving shaft'T is connected to theside walls of the tank by suitable'stuffing boxes forming water-tight bearings.

To the lower part of the hollow vertical shaft F is attached the rotary distributin coil 0 whose three circular sections 0, C,

are in open communication-with and con- .nected by thepipesG, G, which extend radially to and communicate with the interior of the hollow shaft F, as seen in Fi 2.

The circular coil C and pipes are perforated with numerous small holes, as seen trolled by a valve. N are handholds in the a step bearing H, in the A is .jourm Fi 2, and the up er end of the hollow 2 are side of the tank for giving access to the interior.

The overflow tank is composed of a series of superposed sections P, P, P P P P which are connected together by flanged edges by means of bolts and between which flanged edges are secured the margins of a series of baffle plates Y, each of which has at one end a perforated or reticulated section y, as seen in Fi 5. The reticulated sections y of these ba' e lates are arranged in the overflow tank a ternately at opposite ends as seen in Fig. 1, so that the gases or prod- .ucts of combustion are given a tortuous path inrising through said baffle plates as indicated by the arrows.

In the top of the overflow tank are jour-' naled a series of rotary shafts Z, driven by s rocket wheels W and having attached to them beater arms V.

v I is an outlet pipe provided with a suitable valve and. connecting with the bottom of the I overflow tank and M is a down-turned over- The operation of our fume condenser is as follows. Water is admittedto the first tank through the inlet valve J until it completely fills said tank and passes over into the overflow tank through pi e K and fills said overflow tank to the levef of the overflow pipe M. The gases from the furnace stack are then turned into the pipe B and by a suitable blower or other forcing apparatus are made to forcibly enter the hollow shaft F and to issue through the distributing coils in the form of minute jets into the water below the reticulated screen 0 and rising successively through the upper screens 0 O 0, 0.

. This gives intimate contact between the gases and the water for condensing and throwing down any solid constituents .of the gases and all soluble va ors. As the hollow shaft F revolves the distributing coils constantly deliver their jets into new bodies of water and the revolving heaters V in the top of the tank, by their continued agitation, thrash about the fumes and promote an intimate contact of-the fumes and the further precipitation of their solid constituents.

As the gases pass over through the pipe K the enter the ottom of the overflow tank I an ass through the water therein in zi zag fashion as indicated by the arrows, an receive, before escaping at the overflow, a final thrashing from the heaters V. 7

By the above mentioned operations a most intimate contact between the fumes or gases and the water is secured, so as to deliver the i ases into the air in an innocuous condition and save in the bottom of the tanks any valu-' able mineral constituents which may have passed out from the furnace stack.

If desired one or more of the screens 0 can be covered with filter cloth or any other kind of filter material.

We claim- 1. An arrester and condenser for fumes, smoke and gases, comprising a tank having in the center thereof a rotary perforated distributing coil and means for rotating it and a gas pip; leading thereto.

2. arrester and condenser for fumes, smoke and gases, comprising a tank having in the center thereof a-rotary perforated distributing coil, a gas pipe leading thereto and means for rotating the coil, and one or more superposed reticulated screens.

3. An arrester and condenser for fumes, smoke and gases, comprising a tank having in the center thereof a rotary perforated distributing coil, means for rotating it, a gas pipe lending thereto, one or more superposed reticulated screensand one or more revolving beaters.

4. An arrester and condenser-for'fume's, smoke. and gases, comprising a tank made in horizontal sections having marginal flanges bolted together, screens clamped between said sections and a revolving gas distributer in the bottom of the tank. Y

5. An arrester and condenser for fumes, smoke and gases, consisting of a tank, a transverse driving shaft with bevel gear, ,a hollow central shaft connected to and driven by the bevel .gear and having one or more inlet openings, a stationary closed boxing surrounding the hollow shaft about its 0 en ings, an inlet gas pipe extending to this oxing and a perforated distributing coil connected to the hollow shaft.
